Invent This Now

Somebody needs to invent a reverse Coinstar. I go to the grocery store, put bills in the machine and it gives me quarters so can do laundry. No, this is not the same as a change machine. It’s way more high tech and larger and there are backlit plastic panels with sick change related designs on them. It would revolutionize how we use money.
“Oh man, what am I going to do with this huge $10 bill?”
“You could bring it down to Cashstar and have it conveniently turned into 8 quarters, 40 dimes, 65 nickels and 175 pennies!”
“That’s fucking genius. Why would anybody carry around bills when life is so much simpler with coins?”
